ABSTRACT:
Disclosed is an apparatus and method for the recovery of hydrocarbon values from underground hydrocarbonaceous deposits comprising forming an underground reaction zone containing a mass of rubblized hydrocarbonaceous material; forming an essentially surface reaction zone containing a mass of rubblized hydrocarbonaceous material in fluid communication with the underground reaction zone; forming an underground product collection zone for the gathering and collection of hydrocarbon values, said zone being in fluid communication with the surface and underground reaction zones; passing a suitable fluid capable of removing hydrocarbon values from the rubblized material through the surface and underground reaction zones so as to effectively remove hydrocarbon values from such material; and passing the hydrocarbon values to the underground collection zone for recovery.
